Hi,
I can see the problem in your file, but I can’t find a way to duplicate it - I can’t make a dimension that works that way.
If you can tell me how to repeat the problem it would help a lot.
Do you know what you may have done to make the ones that move?
Do you know what version or service release they were made with?
Thanks, Lowell

The two dimensions that were updating incorrectly had history linkage to instance definition geometry. That;s not supposed to be able to happen, and I haven’t found a way to duplicate it.
I’ve changed history update for dimensions to check for it and not update, but would still like to know how it could happen.
